Nuget packages with numbers at the end of the name kill ripple download

[jrios]

Found this when trying to download nuget package: Spark.Web.Mvc3.

It appears that when ripple is trying to parse the version, if it ends in a number, it is prepending that number to the version string to search for.

Here is the log that ripple generated:

[Debug] Searching for Spark.Web.Mvc3 from http://nuget.org/api/v2
[Error] Error executing DownloadMissingNugets
[Error] System.AggregateException: One or more errors occurred. ---> System.ArgumentException: '3.1.7.5.1' is not a valid version string.

Notice the exception points out it search for '3.1.7.5.1' but the version on nuget.org is '1.7.5.1'.

Here is also a stack trace that is included in the ripple log:
